Yep, Twilight, Eclipse, New Moon and the new one comes out in Aug. Plus there's a movie(although I don't know how they can get the people I've pictured so well in my head). All excellent reads.
In fact, my father who is in his 60's has recently been reading tons because there's nothing on t.v. ever. I loaned him my copies and he very much enjoyed them

Right now he's reading the other book she wrote, The Host. He's getting to read it BEFORE me because I haven't had time to get to it yet so I passed it on to him. He's already hooked.
